Overview
A kitchen sink cabinet with room for a tank is where the APEC system goes, sending water through sediment, two carbon blocks, an RO membrane and a final carbon stage. Filtered water fills a tank and flows from its own faucet.
Families tired of bottled water get RO filtration that targets fluoride, arsenic and lead along with taste. Cabinet space and feed pressure matter, and RO sends some water to the drain as it filters.
Who it's for
Families cooking and drinking from the tap who want dissolved minerals reduced will use it daily. Renters who cannot drill for a faucet or homes with weak pressure should look at other filters.
Pros and cons
- Five stages including RO membrane
- Removes fluoride and arsenic
- Large capacity filters
- Quick connect leak resistant fittings
- Tank takes cabinet space
- Needs adequate feed pressure
- Filter life not listed
Performance notes
Output depends on feed pressure and water temperature, both of which change how fast the membrane produces water. Carbon stages protect the membrane from chlorine. A final carbon stage polishes taste from water stored in the tank.
